Well, I decided to try Ubers out, and after my team getting trashed, I knew I needed some MAJOR help. All advice is appreciated.
Lead:
Celebi@Leftovers
Calm
252 HP, 128 Defense, 128 Special Defense
-Stealth Rock
-Thunder Wave
-Recover
-Grass Knot
My lead, sets up stealth rocks which is helpful, paralyzes sweepers. If i manage to save it for later, it can help take hits from Groudon, assuming it is stuck on earthquake and or not carrying a fire move.
Pokemon 2:
Mewtwo@Choice Specs
Timid
252 Special Attack, 252 Speed, 4 HP
-Focus Blast
-Ice beam

This thing is, needless to say, very strong. The move set probably needs work, but he does pretty well.

Trapper Scizor, With so much weak to bug, it kills them with U turn, or forces the switch and I can then counter that. Bullet punch is to finish anything off. Pursuit to catch non weak to bugs switching.
Pokemon 4:
Groudon@Life Orb
Adamant
192 HP, 252 Attack, 56 Speed
